I tried to erase an LTO2 tape with an IBM LTO2 drive. How long should it take ? with
mt -f /dev/nst0 erase
It ran for 50 minutes, I couldn't kill it, halt'ed ubuntu, and the IBM LTO2 drive kept running, I had to cycle power, then hit the eject button.
Is there a better way to erase these tapes.
(You can't degauss LTO2 tapes or they are permanently ruined).
